Adaptive Cruise Control (ACC) system testing

Adaptive Cruise controlAs well as speed, Adaptive Cruise Control allows a driver to maintain a set distance behind the car in front. ACC systems may feature a variety of features, such as auto disengagement and brake warning.
The VBOX3i Vehicle Separation package is suitable for testing to ISO 15622 standard. Adaptive Cruise Control testing and validation can be conducted on the test track using a static DGPS Base Station, or via the Moving Base solution.
Both methods provide a distance between vehicles accuracy of +/-2cm. The Base Station system comprises of:

  • VBOX3i-RTK 100Hz GPS data logger in both the subject and target vehicle
  • DGPS Base Station
  • Telemetry link radios
  • Video VBOX (optional)
  • The Moving Base system comprises of:
  • VBOX3i-SL RTK 100Hz GPS data logger in both the subject and target vehicle
  • Telemetry link radios
  • Video VBOX (optional)

LANE DEPARTURE VBOX KIT

Also available is a Survey Trolley which allows for the accurate surveying of a road bend, necessary when performing ACC tests along a curved lane.
If the vehicle carries the ACC operation data on its CAN Bus, this can be simultaneously logged (and displayed in video if a Video VBOX is also being used) alongside that of the GPS data, giving you an exact comparison between relative vehicle position and onboard strategy data.
Live separation values can be viewed on a laptop or tablet PC whilst testing, and the VBOX File Processor software allows for additional post-processing tasks.
